Note that there are a few chemical formulas that you need to know. Proteins are the most diverse biological molecules with many roles and are necessary for. Regulate metabolism by selectively accelerating chemical reactions. Mechanical support and major components of cells & tissues i. e. , cytoskeleton, keratin in finger-nails & hair, collagen in connective tissues, etc. Intracellular messengers that influence metabolism i. e. , insulin regulates blood"s glucose content. Blood clotting factors to prevent blood loss. Proteins are polymers of amino acids connected in a specific sequence. 8 essential amino acids - must be ingested. 50 to 2000 amino acids in a protein (in a specific sequence) Aa + aa - - > dipeptide + water. Aa + aa + aa - - >tripeptide + 2 waters. Specific backbone: n c c n c c .
